Applegate, 39, and LeNoble, 41, have been dating for nearly three years and became engaged last Valentine’s Day. The pregnancy was announced in July.

In August, Applegate told PEOPLE: “I’ll probably be a little bit hippie and a little bit Type A. I’ll take from what my mother did, which was way hippie and like, ‘Do what you wanna do,’ and bring some things that I know from watching my friends raise their kids. An amalgamation of sorts.”
